Introduction

About this Manual

This manual contains installation, configuration, and operating information for the Extron CrossPoint 300 wideband RGBHV analog matrix switchers.

About the Matrix Switchers

Matrix switchers distribute any input signal to any combination of outputs. The matrix switchers can route multiple input/output configurations simultaneously.

The matrix switchers are single box solutions to complex wideband video and/or audio routing applications (figure 1-1). Each input and output is individually isolated and buffered, and any input(s) can be switched to any one or all outputs with virtually no crosstalk or signal noise between channels.

The matrix switchers are available in a variety of matrix sizes (the matrix size is the number of inputs and outputs):

• CrossPoint 300 84 (eight inputs by four outputs)

• CrossPoint 300 88 (eight inputs by eight outputs)

• CrossPoint 300 816 (eight inputs by sixteen outputs)

• CrossPoint 300 124 (twelve inputs by four outputs)

• CrossPoint 300 128 (twelve inputs by eight outputs)

• CrossPoint 300 168 (sixteen inputs by eight outputs)

• CrossPoint 300 1616 (sixteen inputs by sixteen outputs)

CrossPoint 300 series switchers offer two models of each matrix size: HV for switching RGBHV video signals only, and HVA models for switching RGBHV video and two-channel stereo audio (balanced and unbalanced).

The CrossPoint 300 Series have a video bandwidth of 300 MHz (-3 dB). All models can also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and composite video signals.

All HVA models input and output audio on 3.5 mm, 5-pole captive screw terminals. For all HVA switchers, the audio switching can be either linked with the video (audio follow) or independent of the video (audio breakaway). Adjustable input audio gain and attenuation compensates for level differences between audio inputs.

Each matrix switcher can be remotely controlled via its RS-232/RS-422 port. The matrix switchers are programmed with the Extron Simple Instruction Set™ (SIS™), a set of basic ASCII code commands that provide simple control through a control system or PC without programming long, obscure strings of code. SIS commands can be entered via the RS-232/RS-422 link.

The RS-232/RS-422 port can be connected to a control system, a PC, or the Extron MCP 1000 remote control panel and/or MKP 1000 remote keypad.

The matrix switchers are housed in rack-mountable, metal enclosures with rack ears to fit in a 19" rack.

• The CrossPoint 300 84, 88, 124, and 128 are in a 3U high enclosure.

• The CrossPoint 300 816, 168, and 1616 are in a 6U high enclosure.

Each model has an internal 100 VAC to 240 VAC, 50/60 Hz, 65 watt, autoswitchable power supply that provides worldwide power compatibility.

Tie — An input-to-output connection. Set of ties — An input tied to two or more outputs. (An output can never be tied

to more than one input.)

Configuration — One or more ties or one or more sets of ties. Current configuration — The configuration that is currently active in the

switcher (also called configuration 0)

Global memory preset — A configuration that has been stored. Up to 32 global

memory presets can be stored in memory. Preset locations are assigned to

the input buttons and output buttons. Up to 20 or 32 (depending on the number of input and output buttons) presets can be selected from the front panel for either saving or retrieving. When a preset is retrieved from memory, it becomes the current configuration. All models have 32 presets; on models with fewer than 32 input and output buttons, preset numbers that are too high to be available from the front panel are still accessible under RS-232/RS-422 control.

Features

Video — All switchers input and output wideband RGBHV or RGBS video on

female BNC connectors. They can also switch RGsB, RsGsBs, component/ HDTV, S-video, or composite video.

Bandwidth — The CrossPoint 300 Series switchers provide a minimum of

300 MHz (-3 dB) video bandwidth, fully loaded.

Audio inputs (HVA models only) — Input and output stereo audio inputs,

balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals.

Audio input gain/attenuation (HVA models only) — Individual input audio levels

can be adjusted so there are no noticeable volume differences between sources. Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the RS-232/RS-422 link or the front panel.

Audio output volume (HVA models only) — The audio volume of each output can

be displayed and adjusted through a range of full output to completely silent from the front panel or under RS-232/RS-422 control.

Switching flexibility — The CrossPoint 300 series units provide individually

buffered, independent matrix switched outputs with audio follow and audio breakaway for audio models.

• Tie any input to any or all outputs

• Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time.

• Audio follow — Audio can be switched with its corresponding video input via front panel control or under RS-232/RS-422 remote control.

• Audio breakaway — Audio can be broken away from its corresponding video signal. This feature allows any audio signal to be selected with any video signal simultaneously to one or all outputs in any combination. Audio breakaway switching can be done via front panel control or under RS-232/RS-422 remote control.

presets, and adjustment of audio levels can be performed on the front panel or via the RS-232/RS-422 link. The RS-232/RS-422 link allows remote control via a PC or control system.

• QuickSwitch Front Panel Controller (QS-FPC™) — The front panel controller supports input and output selection, preset creation and selection, audio input gain and attenuation, and audio output level. The front panel features slots for labels that can identify each input and output with text or graphics.

• Windows-based control program — For RS-232/RS-422 remote control from a PC, the Extron Windows-based control software provides a graphical interface and drag-and-drop/point-and-click operation. The Windows-based control program also has an emulation mode that lets you create a switcher configuration file at the home office and then download it for use by the switcher on site.

• Simple Instruction Set (SIS SIS for easy programming and operation.

• Remote control panels and keypads — The matrix switchers are remote controllable, using the optional MCP 1000 master control panel and any combination of optional MCP 1000 slave control panels and/or MKP 1000 slave control keypads. The remote control devices are easy to use and provide tactile buttons for quick selection. Each MCP 1000 can be used for one-touch switching for a particular output and selecting global presets. Each MKP 1000 dedicated to an output can be used to select a different input for that output or to select a preset.

Upgradeable firmware — The firmware that controls all switcher operation can be

upgraded in the field via RS-232/RS-422 without taking the switcher out of service, opening the switcher enclosure, and replacing the firmware chip. Firmware upgrades are available for download on the Extron Web site, www.extron.com, and they can be installed using the Windows control program.

Labeling — The Extron label software ships with every Extron matrix switcher.

You can create labels to place above the front panel input buttons and below the output buttons, with names, alphanumeric characters, or color bitmaps for easy and intuitive input and output selection. Alternatively, labels can be made with any Brother

Global memory presets — 20 or 32 (depending on the model) global memory

presets are a time-saving feature that lets you set up and store input/output configurations in advance. You can then recall those configurations, when needed, with a few simple steps.

Rack mounting — Rack mountable in any conventional 19" wide rack. Front panel security lockout (Executive mode) — If a matrix switcher is installed in

an open area, where operation by unauthorized personnel may be a problem, a security lockout feature can be implemented. When the front panel is locked, a special button combination is required to unlock the front panel controller before it can be operated.

Power — The matrix switcher’s 100 VAC to 240 VAC, auto-switchable, internal

power supply provides worldwide power compatibility.

Installation

Mounting the Switcher

The matrix switchers are housed in rack-mountable, metal enclosures with 19" rack ears. The amount of vertical rack space required for each switcher is as follows:

• The CrossPoint 300 84, 88, 124, and 128 are in a 3U high enclosure.

• The CrossPoint 300 816, 168, and 1616 are in a 6U high enclosure.

If desired, rack mount the switcher as follows:

1. Insert the switcher into the rack, aligning the holes in the mounting bracket with those in the rack.

2. Secure the switcher to the rack using the supplied bolts.

Connections and Rear Panel Features

All connectors for all switchers are on the rear panel. Figure 2-1 and figure 2-2 show a representative sampling of all of the matrix switchers described in this manual.

Figure 2-1 shows the CrossPoint 300 128 HVA.

The CrossPoint 300 84, 88, and 124 are housed in the same 3U enclosure, but have fewer input and/or output connectors to accommodate their smaller matrix sizes.

The CrossPoint Series switchers can also switch RGBS, RGsB, RsGsBs, component video, S-video, or composite video by using four, three, two, or one BNC(s). If switching a video format other than RGBHV, ensure that the same video planes (R, G, B, H/HV, and/or V) are used on the switcher output as on the input.

The switchers do not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

On the 8 x 16, 16 x 8, and 16 x 16 matrix sizes, the connectors for each video plane are grouped together (all of the red inputs grouped together, all of the green inputs grouped, and so on). Ensure that you connect the input on each video plane to the corresponding connector in the correct group (see the drawing at right).

Audio input and output (HVA models only)

By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the front panel or under RS-232/RS-422 control, allows you to select from any one of the audio input sources and route it separately from its corresponding video source. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Switcher Software for details.

Connections for balanced and unbalanced audio inputs — Each input has a

3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each switcher, but you must supply the audio cable. See figure 2-3 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

Each switch provides the option of selecting either 510 ohms or 75 ohms. The 75 ohms position is required only for an input with non-TTL sync, greater than 5 Vp-p. The normal position is 510 ohms.

An input that produces an out of sync display, a display that is rolling vertically and/or tearing horizontally, could indicate a non-TTL sync input. A device that is known to output non-TTL sync levels (greater than 5 Vp-p) should be connected to one of the inputs with sync termination switches, and the switches for that input should be set to the 75 ohm position. If you are not sure, check the specifications in the user’s manual for the input device.

Front Panel Operations

The following paragraphs detail the power-up process and then provide sample procedures for the following actions:

• Creating ties, sets of ties, and configurations

• Changing a configuration

• Viewing ties, sets of ties, and configurations

• Muting and unmuting outputs

• Saving a preset

• Recalling a preset

• Viewing and adjusting the output volume

• Viewing and adjusting the input audio level

• Locking the front panel

• Performing front panel resets

• Reading and setting the RS-232/RS-422 Remote port settings

Power indications

On all models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that flashes the front panel button indicators and then turns them off. An error-free power up self-test sequence leaves the RGBHV LED and the Audio LED on, and all other LEDs unlit.

The current configuration and all presets are saved in non-volatile memory. When power is applied, the most recent configuration is retrieved. The previous presets remain intact.

If an error occurs during the self-test, the switcher locks up and does not operate. If your switcher locks up on power-up, call the Extron S Hotline.

1. Press the Esc button to clear any input LEDs, output LEDs, or control LEDs that are lit.

2. Select to configure video, audio, or both by pressing the RGBHV button and/or Audio button.

3. Select the desired input and output(s) by pressing the input and output buttons.

To indicate potential ties, output LEDs blink when an output is selected but not tied to the input.

To indicate current ties, output LEDs light steadily when an input is tied to the output.

To clear unwanted outputs, press and release the output buttons associated with the lit LEDs. To indicate potential unties, output LEDs blink when an output is deselected but not untied from the input.

4. Press and release the Enter button to accept the new tie or to break an existing tie.

5. Repeat steps 1 through 4 to create additional ties until the desired configuration is complete.

• Only one video input and one audio input can be tied to an output.

• If a tie is made between an input and an output, and the selected output was previously tied to another input, the older tie is broken in favor of the newer tie.

• To indicate current ties, output LEDs light when an input is selected. To clear unwanted outputs, press and release the associated output buttons.

• If, when configuring video and audio ties, the Audio LED blinks and the RGBHV LED is on after selecting an input or output, the LEDs indicate audio breakaway, meaning that the audio ties are not the same as the video ties for that input.

• If an input with no tie is selected, only that input’s LED lights.

• When the RGBHV and Audio LEDs are on, if an input with an audio tie but no video tie is selected, the input’s LED lights and the Audio LED blinks.

• As each output is selected, the associated output LED blinks to indicate a tentative tie. LEDs for output(s) that were already tied to the input light steadily. Outputs that are already tied can be left on, along with new blinking selections, or toggled off by pressing the associated output button.

The current configuration (configuration 0) can be saved as a preset in any one of 32 preset memory addresses. Preset locations are assigned to the input buttons and output buttons. Up to 20 or 32 (depending on the number of input and output buttons) presets can be selected from the front panel to be either saved or retrieved. When a preset is retrieved from memory, it becomes the current configuration.

• Only the audio and video ties are stored and recalled; audio gain settings are not saved, and they do not change when a preset is recalled.

• Presets cannot be viewed from the front panel unless recalled as the current configuration. Presets can be viewed using Extron’s Windowsbased control program. See Chapter 5, Matrix Software, for more details.

• The current configuration and all presets are stored in non-volatile memory. When power is removed and restored, the current configuration is still active and all presets are retained.

• When a preset is recalled, it replaces the current configuration, which is lost unless it is also stored as a preset. The recalled preset overwrites all of the current configuration ties in favor of the preset configuration ties.

• All models have 32 presets; on models with fewer than 32 input and output buttons, preset numbers that are too high to be available from the front panel are still accessible under RS-232/RS-422 control.

Reading the displayed value

There are 65 steps of volume attenuation, with 1 dB per step (button push), except for 0-to-1, which is 35 dB. At maximum attenuation, no input LEDs are lit, 98 dB of attenuation is applied, and the audio output is effectively muted. At no attenuation, all input LEDs are lit and the output volume is equal to the input signal plus any gain or attenuation that is applied to that specific input using the input audio level adjustment. See Viewing and adjusting the input audio level (audio models). Other than the minimum and maximum volume, the switchers indicate the volume differently, depending on number (12 or 16) of input LEDs. See the table on the next page to read the volume display for each display scheme.

For each display scheme, the input LEDs blink or light sequentially to indicate the approximate volume of the selected output. Volume is defined as a percentage of the input audio signal that is applied to the output. From 0% of volume, the first Esc (

) button push applies 5.5% of the input audio signal. From 5.5% on, each ) push applies 1.5% more of the input audio signal to the output:

Esc (

This section is a detailed look at reading the output volume display on the switcher’s front panel. If you do not need read the exact value of the volume setting, skip this section.

• Push Esc (

! All switcher input button configurations — Indicated by the Input 1

button blinking slowly.

• Push Esc (

! Switchers with 12 input buttons — Indicated by the Input 1 through 4

buttons lit steadily.

! Switchers with 16 input buttons — Indicated by the Input 1 through 5

buttons lit steadily and the Input 6 button blinking.

When all input LEDs are lit for any switcher model, the audio output is 100% of the audio input level.

Another way to view the volume level is to think in terms of the attenuation that is applied to the output. Attenuation reduction is indicated by the lit or blinking input LEDs: when fewer input LEDs are lit, attenuation is greater (and the volume is quieter).

• At minimum volume, all input LEDs are unlit and 98 dB of attenuation is applied to the output. The audio output is effectively muted.

• The first step of volume increase causes the Input 1 LED to blink (slowly, in the case of switchers with 12 input buttons). Attenuation is reduced by 35 dB (63 dB of attenuation is applied to the output).

• The second step of volume increase reduces the attenuation by an additional 1 dB (62 dB of attenuation is applied to the output).

• Successive steps of volume increase cause consecutive LEDs to first blink, then light steadily.

Performing a hard reset from the rear panel

The hard reset function restores the switcher to the original factory default settings. All user files and settings are maintained. Perform a hard reset as follows:

1. If necessary, turn off power to the switcher.

2. Press and hold the Reset button on the rear panel while you apply AC power

to the switcher (figure 3-62).

Press and hold the Reset button while you apply power to the switcher.

RESET

The switcher flashes the LEDs and then turns them off.

Continue to hold the Reset button until all input and output LEDs return to unlit and the RGBHV or Video and Audio LEDs turn on.

Figure 3-62 — Hard reset

A hard reset returns the switcher to the default (factory) firmware configuration. The switcher continues to operate using this firmware until you either cycle power, in which case the switcher begins to use the mostrecently installed firmware update, or install a new firmware update.

Power

Release the Reset button.

Optimizing the Audio (HVA Switchers)

Each individual input audio level can be adjusted within a range of -18 dB to +24 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows:

1. Connect audio sources to all desired inputs and connect the audio outputs to output devices such as audio players. See Audio input and output (HVA models only), in chapter 2, Installation. For best results, wire all of the inputs and the outputs balanced.

2. Power on the audio sources, the switcher, and the audio players.

3. Switch among the inputs (see Creating a configuration, in this chapter),

listening to the audio with a critical ear or measuring the output audio level with test equipment, such as a VU meter.

4. As necessary, adjust the input audio level of each input (see Viewing and adjusting the input audio level (HVA models), in this chapter) so that the

approximate output level is the same for all selected inputs.

This section gives recommendations on what to do if you have problems operating the switcher, and it describes an actual image problem that Extron has encountered.

General checks

1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if the Esc LED flashes one time when you push the Esc button.

2. Ensure an active input is selected for output on the switcher.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S

Plasma display S-video problem

Extron has encountered a problem when a matrix switcher with two or more video planes routes S-video that is output by some video conference codecs. Some codecs change the DC offset on the chrominance (C) so that it is very different from the level on the luminance (Y). This can cause a plasma display to come up in the wrong size mode.

With the matrix switcher taken out of the system, the plasma works fine. It looks like a problem with the matrix switcher, but it is not. The matrix switcher boosts the bad codec output, which makes the plasma go to the wrong setting.

Solution: Try placing an Extron video DC block adapter, part #26-495-02, on the luminance (Y) input to the switcher from the codec.

Configuration Worksheets

Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-43 and use one for each preset configuration. The worksheet accommodates all of the matrix switcher models documented in this manual. Cross out all unused or inactive inputs and outputs. Use different colors for video and audio.

Worksheet example 1: Entering system equipment

Figure 3-63 shows a worksheet for a CrossPoint 300 128 HVA in a fictional organization with the system hardware annotated. Inputs 10 and 11 and output 7 have no connections in this organization, so they have been crossed out on the worksheet. On this example, preset 3 is used for the weekly status meeting. Choose your own method of notation.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through the RS-232/RS-422 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = response character string. A string is one or more characters.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

Vmtnn•x The switcher initiates the Vmt message when a video output mute is toggled on or

Exen The switcher initiates the Exe message when front panel lock is toggled on or off

from the front panel. “n” is the front panel lock status: 1 = on, 0 = off.

Switcher Error Responses

When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (too large) E10 — Invalid command E11 — Invalid preset number (too large) E12 — Invalid output number (too large) E13 — Invalid value (out of range) E14 — Illegal command for this configuration E17 — Timeout (caused only by direct write of global presets) E22 — Busy E25 — Device not preset E28 — Bad filename/File not found

Using the Command/Response Table

The command/response tables begin on page 4-5. Lower case letters are acceptable in the command field except where indicated for the gain and attenuation commands. The table below shows the hexadecimal equivalent of each ASCII character used in the command/response table.

The direct write of a global preset should always be preceded by a clear global preset command of that same preset number, as shown below. In a directly-written preset, each output position’s tied input (or no tied input) remains unchanged unless overwritten or cleared.

If you do not clear a global preset number before you directly write a global preset to that number, ties that are part of the previous version of the specified presets with the same number can unexpectedly become part of the newly-created preset.

Matrix Software

Two software programs accompany the CrossPoint 300 switchers:

• The Extron Matrix Switcher+ Control Program (Extron part #29-015-01), which communicates with the switcher via the RS-232/RS-422 port, provides an easy way to set up ties and sets of ties.

• The Extron Button-Label Generator, which allows you to design and print labels for the matrix switcher’s front panel buttons.

Both programs are compatible with Windows 95/98, Windows NT, Windows ME, Windows 2000, and Windows XP. Updates to these programs can be downloaded from the Extron Web site (http://www.extron.com).

Matrix Switchers Control Program

Installing the software

The program is contained on a set of 3.5-inch diskettes. Load and run the program from the hard drive.

To install the program from the floppy disk to the hard drive, run Setup.exe from the floppy disk and follow the instructions that appear on the screen. The program occupies approximately 1 MB (megabyte) of hard-drive space.

By default, the Windows installation creates a C:\MTRX50 directory and places two icons (MATRIX Switcher+ Control Program and MATRIX Switcher+ Help) into a group or folder named “Extron Electronics”.

The program was designed to control most Extron matrix switchers, but its operation is limited to the features and configuration of your switcher.

Many items found in the Matrix Switcher+ Control Program are also accessible via front panel controls (see chapter 3, Operation) and under SIS control (see chapter 4, Programmer’s Guide). The Matrix Switcher+ Help Program provides information on settings and on how to use the control program itself.

1. To run the Matrix Switcher+ Control Program, double-click on the Matrix Switcher+ Control Program icon (shown at left) in the Extron Electronics group or folder.

The Comm Port Selection window (figure 5-1) appears.

Figure 5-1 — Comm port selection window

2. Choose either the comm port that is connected to the matrix switcher’s

RS-232/RS-422 port or Emulate.

Although IP [LAN] is available for selection, the switcher does not have an Ethernet port. Do not select IP [LAN].

! If you selected a comm port, check the baud rate displayed in the comm

port selection window. If you need to change the baud rate, click on the Baud button and double-click on the desired baud rate.

Available rates are 9600, 19200, 38400, and 115200. The default is 9600.

The switcher can operate at 9600, 19200, 38400, or 115200 baud rates. See

RS-232/RS-422 and baud rate indication and selection in chapter 3, Operation, to identify the selected baud rate from the front panel.

Click Ok and proceed to step 3.

! If you selected Emulate, click Ok and see Using emulation mode on page 5-

10.

3. The Extron Matrix Switcher+ Control Program window (figure 5-2 and

figure 5-3) appears. The window displays the current configuration of the attached matrix.

The firmware upgrade utility provides a way to replace the firmware that is coded on the switcher’s control board without taking the switcher out of service, opening the switcher enclosure, and replacing the firmware chip.

Update the switcher firmware as follows:

1. Visit the Extron web site, www.extron.com, select the CrossPoint 300 product

category, and select the latest firmware file for download. Note the folder to which you save the firmware file.

2. Start the Matrix Switcher+ Control Program and connect to the matrix

switcher. See Using the software in this chapter, steps 1 through 3, starting on page 5-3.

3. Click Tools > Update firmware. The Extron Firmware Loader utility appears

(figure 5-4).

a. Click Upload. The Firmware Update window appears. b. Click OK. The open file window appears.

Figure 5-4 — Open window

4. Navigate to the folder where you saved the firmware upgrade file. Select the

file.

Valid firmware files must have the file extension .S19. Any other file extension is not a valid firmware upgrade.

The original factory-installed firmware is permanently available on the switcher. If the attempted firmware upload fails for any reason, the switcher reverts to the factory-installed firmware.

5. Click the Open button. A status bar, which shows the progress of the upload, appears in the Firmware Loader window (figure 5-5). The firmware upload to the switcher may take several minutes.

Figure 5-5 — Firmware Loader status indicator bar, switcher reset, and firmware update

Once the status bar has progressed fully from left to right across the indicator window, the firmware loader utility resets the switcher (figure 5-5).

If the firmware loader utility exits before the status bar has progressed completely across the indicator window, try using a control cable with only pins 2, 3, and 5 connected. If necessary, modify the cable by removing pins or cutting wires.

6. When prompted, confirm that the firmware version displayed in the firmware loader is correct. Click Ok in the Firmware Update prompt window.

7. Click the Exit button to exit the firmware loader utility.

The firmware loader utility increases the serial port’s baud rate to 115,200 to speed up the upload process. Occasionally, the firmware loader may be unable to return the serial port to its earlier baud rate, in which case communications with the switcher may not be possible. If you are no longer able to communicate with the switcher after the firmware upload completes, see

Selecting the RS-232/RS-422 protocol and baud rate in chapter 3, Operation, on page 3-35.
